Several excited states of the neon atom are important in the operation of the helium-neon laser. In these excited states, one electron of the neon atom is promoted from the 2p level to a higher energy orbital. An excited neon atom with a 1s2s22p5s7 electron configuration can emit a photon with a wavelength of 3391 nm as it makes a transition to a lower energy state with a 1s22s2p4p electron configuration. Other transitions are also possible. If an excited neon atom with a 1s 2s22p5s electron configuration makes a transition to a lower energy state with a 1s22s 2p 3p electron configuration, it emits a photon with a wavelength of 632.8 nm. Find the wavelength (in nm) of the photon that would be emitted in the transition from the 1s22s22p 4p electron configuration to the 1s22s22p% 3p' electron configuration.
